Product Description:

The MHD112B-024-NG1-AN is a servo motor manufactured by Bosch Rexroth Indramat as part of the MHD Synchronous Motors series. Designed for closed-loop industrial drives, it converts electrical input from a compatible inverter into precise rotary motion for positioning axes, spindle drives, and material-handling equipment on factory floors. Its B-length stator, plain shaft construction, and integrated feedback elements allow tight velocity and torque control while fitting into medium-frame machinery. The motor is supplied with a holding brake so axes can be secured when power is removed.

At standstill the motor delivers a continuous torque of 28.0 Nm, enabling it to hold loads without overheating. Heat in the windings is removed by liquid cooling built into the housing, so the rated torque can be maintained inside sealed enclosures. A 192 mm mounting flange aligns with standard frames, simplifying retrofits. Rotor position is monitored by a Digital servo feedback (HSF) encoder that feeds high-resolution signals to the drive. Power exits on side A through an output connector and is transmitted by a plain shaft, which avoids keyways and lowers vibration during frequent reversals.

For emergency stops or vertical axes, the integrated brake supplies 22.0 Nm of retentive torque, engaging automatically when the drive removes excitation. Accurate concentric mounting is supported by a 130 mm centering diameter, which keeps radial run-out low and protects the shaft seal. The stator winding is identified by code 024, matching the inductance and resistance that the manufacturer calibrates for medium voltage controllers. Because the motor belongs to size 112, its external dimensions and inertia fall within a standardized envelope that can share mechanical brackets with other units in the MHD range. Relative position detection in the encoder permits homing sequences after power-up, and a shaft seal limits lubricant migration into the feedback chamber.
